Figure 1

(a) Standard deviation of the Tmin (°C) from 1st Nov to 28th Feb over the period 1982 to 2013. (b) Spatial distribution of significant SST (°C) anomalies during TYPE1 events. (c) same as (b) but for TYPE2 events. (d) Significant Tmin (°C) anomalies associated with TYPE1 events (e) same as (d) but associated with TYPE2 events. (f) The first mode of EOF of Tmin anomalies. (g) The second mode of EOF of Tmin anomalies. (h–k) Significant air temperature anomalies (°C) at 1000 hPa, 850 hPa, 500 hPa and 300 hPa respectively during TYPE1 events. (l–o) Significant air temperature anomalies (°C) at 1000 hPa, 850 hPa, 500 hPa and 300 hPa during TYPE2 cold wave events. Significance is at 99% using two-tailed Student’s t-test. The rectangular box in (a), (f) and (g) represents the region used to identify the cold wave events over India.
